Specific embodiment
In order to illustrate the technical solution of the embodiments of the present invention more clearly, below will be to needed in the embodiment attached
Figure is briefly described, it should be apparent that, drawings in the following description are some embodiments of the invention, common for this field
For technical staff, without creative efforts, it is also possible to obtain other drawings based on these drawings.
It please refers to, operation tweezer includes hand-held device 10, clamp assemblies 20, the hand-held device 10 under a kind of minimally invasive retina
It is arranged and connect with clamp assemblies 20, the hand-held device 10 includes operation handle 101, quill 102, several umbrella frames 103, consolidates
Determine sleeve 104, the rear end of the operation handle 101 is fusiform, and the front end of operation handle 101 is column, quill 102 with
The front end of operation handle 101 is arranged connection, and the middle-end of quill 102 and one end of umbrella frame 103 are hinged, and umbrella frame 103 is in radiation
Shape is distributed on quill 102, and the middle-end of umbrella frame 103 and the rear end of fixes sleeve 104 overlap, the front end of fixes sleeve 104
It is arranged and connect with the front end of quill 102, the front end of fixes sleeve 104 is additionally provided with L-type groove 1041, L-type groove 1041
Front end extends on the end face of the front end of fixes sleeve 104, and the clamp assemblies 20 include connection sleeve 201, push support
203, the side wall of movable needle tubing 204, spring part 205, supporting rod 206, the rear end of the connection sleeve 201 is equipped with chuck 202,
It is connect with being arranged with the L-type groove 1041 of fixes sleeve 104, pushes support 203 to be located in connection sleeve 201, push support 203
For tubulose, the front end of support 203 is pushed to be fixedly connected with movable needle tubing 204, spring part 205, which is located at, pushes support 203 and connection
Between the front end of sleeve 201, supporting rod 206 is arranged and connect with support 203 and movable needle tubing 204 is pushed, and after supporting rod 206
It holds across pushing the side wall of support 203 to be fixedly connected with sleeve 201 is connect, the front end of supporting rod 206 sets identical there are two having
The prong 2061 of radian, and two prongs 2061 are to same lateral bend.
Further, the umbrella frame 103 is equipped with groove, to increase the frictional force between finger and umbrella frame 103.
Due to eyes be spherical.If the prong 2061 of supporting rod 206 be it is linear, in operation, fork
Tooth 2061 is just not easy to fit to ocular surface, to just need constantly adjustment tweezers angle so that tweezers can press from both sides during operation
Firmly it is proliferated film.And prong 2061 is arc, so that it may fit to ocular surface, in mobile tweezers, be equivalent to reduce
The operation of one dimension easily facilitates personnel's operation.The contact area of tweezers and eyes is smaller simultaneously, can reduce iatrogenic damage
Wound.
Medical staff is when operating hand-held device 10, finger, umbrella frame 103, quill 102 and the operation handle of people
101 constitute slider-rocker mechanism, and when finger mediates umbrella frame 103, one end that umbrella frame 103 is connect with quill 102, which drives, lives
Moving sleeve 102 travels forward along operation handle 101.
Hand-held device 10 with clamp assemblies 20 after connecting, the front end of the quill 102 of hand-held device 10 and promotion branch
Seat 203 contacts, and the front end of quill 102 and the front end of fixes sleeve 104 are on the same end face.Due to fixes sleeve
104 with to connect the chuck 202 that sleeve 201 has passed through on L-type groove 1041 in fixes sleeve 104 and connection sleeve 201 solid
Fixed connection, therefore relative motion will not occur in the axial direction for fixes sleeve 104 and connection sleeve 201.When 103 promotion activity of umbrella frame
When sleeve 102 travels forward, the promotion support 203 that just will push in connector sleeve cylinder 201 travels forward.Since spring part 205 presss from both sides
It is pushing between support 203 and the end for connecting sleeve 201, with travelling forward for support 203 is pushed, spring part 205 can quilt
Compression, spring part 205 will reset after hand unclamps.Simultaneously push support 203 and activity needle tubing 204 synchronize travel forward
When, supporting rod 206 is fixed, therefore the prong 2061 of 206 front end of supporting rod can be made to shrink.
Tweezer is operated when in use under minimally invasive retina of the invention, first by the L of the fixes sleeve 104 of 10 front end of hand-held device
Type groove 1041 is directed at the chuck 202 of clamp assemblies 20, and fixes sleeve 104 is caught in the connection sleeve 201 of clamp assemblies 20,
When chuck 202 reaches longitudinal bottom of L-type groove 1041, hand-held device 10 is rotated, makes chuck 202 in L-type groove 1041
Transverse movement, so that hand-held device 10 and clamp assemblies 20 is fixed.When operation, hand mediates umbrella frame 103, makes quill 102
Travel forward, so push clamp assemblies 20 promotion support 203 and with push support.
The above disclosure is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, those skilled in the art can understand all or part of the processes for realizing the above embodiment, and wants according to right of the present invention
Made equivalent variations is sought, is still belonged to the scope covered by the invention.
